Genitalia. Uncus short, stout, with broadly rounded tip; beneath the uncus, inside the tegumen, a badly sclerotized structure with numerous, hair-like setae; accessory claspers very broad, at the margin closest to the valves, at the inner surface, a row of short, straight to slightly bent, proximally very short, spoon-like inflated, stout and thickened setae; slightly beyond that row a second row of heavily modified, axe-like, stout and thickened setae; valves moderately long, at the inner surface postbasally with two short and stout setae; valves constricted medially, the spatulate distal fourth slightly bent upwards, at the inner surfcae 1 - 2 irregular rows of short to very short, straight, stout and thickened setae.

Genitalia. Not investigated.

Externally, M. imperfectella resembles Micropterix aruncella (Scopoli, 1763) quite well, but can be distinguished mainly by the incomplete fascia at 1/2 and the prominent spot at 3/4. In the male genitalia, M. imperfectella is completely different from M. aruncella. So far, the of M. imperfectella has not been investigated. Therefore, we do not know wether it also lacks the spots on the forewing like in M. aruncella.

Phylogeny: Judged from the male genitalia and the external appearance, M. imperfectella does not have any close relatives in the genus. DNA-data are lacking too.
